Worker productivity and computer vision syndrome

If you use a computer at work, you probably already know that a long day of staring at your screen can lead to eye strain, tired eyes, headache, muscle aches and other symptoms of computer vision syndrome (CVS). But you may not know that CVS also can cause work mistakes and lost productivity.

And
if you own a company, you might be interested to know that studies
suggest you can increase profits by providing your employees vision care benefits and computer glasses to help boost productivity, decrease errors and reduce worker disability claims.

Is Computer Vision Syndrome Really A Major Problem At Work?

According
to the American Optometric Association (AOA), the most frequent health
complaints among computer workers are vision-related. Studies indicate
that 50 to 90 percent of computer users suffer from visual symptoms of
computer vision syndrome. These symptoms include eye strain, dry eyes, eye irritation, blurred vision and double vision.

With
more and more of us using a computer at work, CVS is becoming a major
public health issue. The AOA reports that a survey of optometrists found
that approximately 10 million eye exams are performed annually in the United States due to vision problems related to computer use.

CVS And Worker Productivity

A
study conducted by the University of Alabama at Birmingham (UAB) School
of Optometry examined the relationship between the vision of computer
workers and their productivity in the workplace.

This study found:

A
direct correlation between proper vision correction and productivity.
This relationship particularly is evident with complex and/or repetitive
computer tasks such as data entry.

A direct correlation between
proper vision correction and the time required for a computer worker to
perform a task. Computer-related tasks took much longer when the
subjects wore glasses with less than the optimum correction.

Reduced productivity even among computer users who were unaware they had vision problems. Computer users with small refractive errors may not notice any vision discomfort. But without proper vision correction, their performance on a specific task can suffer significantly — by as much as 20 percent.

"Our data strongly
suggest that improving the visual status of workers using computers
results in greater productivity in the workplace, as well as improved
visual comfort," said Kent Daum, OD, PhD, the study's chief
investigator.

Computer Eyewear And The Bottom Line

According
to the UAB study, the economic benefit to employers of providing
computer eyewear to their employees can be determined by measuring the
average gain in productivity for computer workers over a one-year
period, and dividing this productivity gain by the costs associated with
the eyewear.

For example:

If an employer pays a
computer worker $125 per day to process claims, and that employee
processes 100 claims daily, the cost to the employer is $1.25 per
processed claim.

If computer glasses could increase the claim
processor's productivity by just 5 percent (a conservative estimate in
light of the UAB study results), the worker could now process five
additional claims per day, for a daily cost savings of $6.25 (5 x
$1.25).

If you assume the worker is on the job 250 days per
year, this is an annual cost savings of $1,562 for the employer (per
employee).

If the company pays the cost of the worker's annual
eye exam and computer glasses (let's say it's $300), this is an annual
net cost savings to the company of $1,262 per computer worker.

And if productivity is improved 10 percent, the cost savings more than double.

The
UAB study also suggests computer vision benefit programs can add
significant economic benefits to companies with large numbers of
computer-using employees. Study results show that:

Providing
computer vision care to all employees who use computers, even those who
are not experiencing CVS symptoms, results in significant productivity
gains and cost savings for employers.

Musculoskeletal problems,
which may be caused by computer-related vision problems, can potentially
be minimized or eliminated by including computer vision care in a
comprehensive vision care benefits program.

Employees performing
tasks with particularly demanding visual requirements, such as
accounting, document editing, CAD (computer-assisted design) work,
electronic design and engineering, could benefit even more from computer
eyewear than the average computer worker.

A computer vision benefits program likely will also lower incidence of workers' compensation claims among computer workers.
